"CHURN.

SPECIFICATION forming part of Letters Patent No. 603,091, dated April 26, 1898.

Application filed September 20, 1897. Serial No. 652,332. (No model.)

To all whom it may concern;

Be it known that we, ANDREW M. LANCE and FRANKLIN J. FLooKER, of Bellowsville,

, ful Improvements in Ohurns and we do hereby declare the following to be a full,clear,and exact description of the invention,such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to improvements inchurns,and has particular reference to a rocking churn of simple construction which is so arranged with respect to its rockers and rocker-supports that the churn-body is held normally in a centered or horizontal position.

A further object of the invention is to so arrange the rocker-frame as to removably hold the churn-body in proper place.

The invention consists in the novel features of construction hereinafter fully described and claimed,and illustrated by the accompanying drawings, in which Figure 1 is a perspective view of our improved churn. Fig. 2 is a side elevation, a portion of the track-casing beingbroken away to disclose the curved tracks. Fig. 3 is a detail view of the rocker-frame. Fig. 4 is a similar view of one of the brackets for uniting the churn with the rocker-frame.

The frame proper or support consists of the horizontal parallel track casings A, each formed with integral sockets to receive legs B and on their inner sides flanged to form the curved tracks 0. At regular intervals these tracks are formed with teeth or projections D, adapted to take in notches E of the semicircular rocker E, thus holding the latter in proper position upon the tracks. These rockers E are constructed with depending arms F, which are united by rods G, the latter serving to make rigid the rocker-frame.

The elongated churn-body H is adapted to pass loosely between rockers E, and on opposite sides thereof are secured to brackets I, which overhang the upper horizontal sides 6 of rockers E, the said upper sides being notched to receive the brackets, as shown. Hooks J are secured to the support and adaptto each other, as they are when the rockers rest upon the tracks,the tendency of the rockers is to turn to the lowermost part of the tracks and there remain, and in so doing the churn is kept normally centered or in horizontal position.

When the churn is rocked,the cream rushes to the lowermost end thereof at each vibration, and the entire weight of the cream is exerted toward holding the churn-body at the greatest inclination assumed during its oscillation, or, in other words, in an upwardly-inclined position at the end of the track. When the track is flat or horizontal, this tendency must be overcome by the operator at each oscillation. The momentum occasioned by the rush of cream is entirely lost, and there is no automatic actuating tendency. With ourimprovement, consisting of a track of less curvature than the rockers, the momentum of the churn at each oscillation serves to run the latter upward on the curved track, and the latter not only serves to arrest or limit the oscillations, but also starts the churn on its next reverse oscillation. There is no lost or wasted power,as when a straight track is used, the whole tendency of the churns movement being to continue to oscillate, with comparatively little exertion necessary on the part of the operator to keep the churn in motion. Moreover, the latter automatically centers itself upon the traclr in upright position when coming to rest.

While we have found the construction of the support here shown, as also that of the rocker-frame, to be simple and convenient, yet we do not desire to limit ourselves to this particular arrangement, as manifestly the same may be varied in numerous particulars without departing from the spirit of our invention; and the same privilege to change or alter the invention in other minor details is also reserved.

Having thus fully described our invention, What We claim, and desire to secure by Letters Patent, is

1. An improved churn, including a base or track, a r0cker-frame adapted to oscillate thereon, said frame consisting of rockers E, each having depending arms F, the corresponding arms of the rockers being connected by rods G, whereby a transversely-rigid frame is formed with unobstructed space between the rockers proper, and a churn-body removably seated between and sustained-by the rockers, substantially as shown and described.

2. An improved churn, includinga base or ANDREW M. LANCE. FRANKLIN J. FLOCKER.
